Siheyuan: I am different He Yuzhu

Just as Xu Wude and Xu Damao were imagining Xu Damao's future, He Yuzhu finally remembered how to improve the nutrition of the canteen meals. People in this era have insufficient intake of fat and protein, and can only rely on carbon water to replenish energy, so everyone seems to have a large appetite. Insufficient fat intake is caused by the environment, and He Yuzhu has no good solution. However, He Yuzhu did think of a good thing for insufficient protein, that is, artificial meat made from soybeans. Soybeans can be made into artificial meat, so that all soybeans can be used. The bean cakes left after the oil is squeezed out of the soybeans cannot be eaten in large quantities.

Now that he had figured out a method, He Yuzhu was no longer so entangled. In modern times, artificial meat is produced in special workshops. With a few simple artificial meat-making equipment, only 1-2 people can easily produce it. For He Yuzhu, the biggest problem now is how to solve the production equipment. After all, people in his previous life only saw how machines processed artificial meat in artificial meat workshops. He only knew the general principle of how machines processed artificial meat, but he didn't know what the internal structure of the machine was like. He had to study this bit by bit.

However, with his strong memory, He Yuzhu clearly remembered the process flow of soy artificial meat: bean cake → crushing → mixing → extrusion and puffing → drying. The most difficult thing for He Yuzhu was to solve the extrusion and puffing machine. The other steps were easy to solve. Next, He Yuzhu only needed to invent the screw extrusion and puffing machine. This machine equipment could not be made in a short time. After He Yuzhu wrote down the problems that needed to be solved in his notebook, he stopped thinking about this problem. Next, he would consider finding a place to make a prototype first, so that he could try it little by little.

So when it was weekend, He Yuzhu rode his bicycle and took the blueprint he had drawn to look for a blacksmith shop that could process the iron. He first came to the blacksmith shop in Nanluoguxiang, which was the closest to his home. He had bought a hoe and a sickle from this blacksmith shop before. He parked his bicycle in front of the blacksmith shop, listened to the rhythmic sound of blacksmithing coming from the shop, and walked into the blacksmith shop with the blueprint. He shouted to the blacksmith Sun who was working on the ironwork: "Master Sun, can you stop the work in your hands? I want to ask you something." Blacksmith Sun's hearing was poor due to long-term blacksmithing, so He Yuzhu could only shout loudly.

"Xiao He, please go out first and wait for me outside for a while. I will finish making this thing soon." Blacksmith Sun said loudly.

"Okay, Master Sun, I'll go out first and wait for you at the door of the shop." He Yuzhu said loudly. After that, He Yuzhu turned around and walked out of the blacksmith shop.

He Yuzhu stood at the door of the blacksmith shop and listened to the rhythmic "ding ding ding" sounds of iron hammering coming from inside the shop. He couldn't help but think of the famous saying of Teacher Huang Hong on the Spring Festival Gala, "Eighty, eighty..." So He Yuzhu began to silently make sounds for the blacksmith Sun in the shop, "Forty, forty..." He Yuzhu was having a lot of fun alone and was getting more excited when suddenly the sounds of iron hammering stopped in the blacksmith shop. After a while, blacksmith Sun came out.

Sun Tiejun greeted He Yuzhu enthusiastically: "Xiao He, what do you want to see me for?"

He Yuzhu smiled and said, "Master Sun, I want you to make a few things for me. Do you think you can do them?" After that, He Yuzhu handed the drawings in his hand to Sun the blacksmith. Sun Tiejun took the drawings handed over by He Yuzhu, put on the reading glasses hanging around his neck, and looked at them carefully.

After looking at it for a while, Blacksmith Sun smiled and said, "Xiao He, you think too highly of your master Sun. I can't make this thing. The thing on your drawing needs a lathe to make it."

He Yuzhu felt a little embarrassed after hearing what Sun the blacksmith said, so he quickly said, "I'm sorry, Master Sun, I'm a little abrupt. Do you know where in our city of Sijiu can make this thing on my drawing?"

Blacksmith Sun laughed and said cheerfully, "It's okay, Xiao He. There is actually someone in our city who can make what you drew on the blueprint. But I don't know if he can do it now. He is a little older than me."

He Yuzhu asked quickly, "Master Sun, where does the old master you mentioned live? I can go and ask him and find out."

Blacksmith Sun thought for a moment and said, "The man I'm talking about has the surname Zheng. Because he has a weird temper, everyone calls him Weird Zheng. His ancestors were all masters of the Imperial Household Department. He lives a little far from us, in Yangweiba Hutong. I don't know exactly where he lives. You can go and ask around. People nearby should know him."

He Yuzhu said sincerely: "Thank you, Master Sun, I'm sorry for delaying your work."

Blacksmith Sun waved his hand nonchalantly and said with a smile: "It's okay, go ahead, I just need to take a break."

After He Yuzhu said goodbye to Blacksmith Sun, he rode his bicycle in a hurry to the direction of Yangwei Hutong. He stopped from time to time to ask how to get to Yangwei Hutong. He finally arrived at Yangwei Hutong while walking and asking. After entering the hutong, He Yuzhu found an old lady who was sewing shoe soles at the gate and asked, "Auntie, do you know how to get to Zheng Laoguai's house?"

The old lady said enthusiastically, "Old Weird Zheng's house is easy to find. Just walk along the alley and you'll find his house when you reach the blacksmith's shop."

He Yuzhu said politely, "Thank you, Auntie." After that, He Yuzhu rode his bicycle into the alley. After a while, he saw a blacksmith shop, but he didn't hear any iron-forging sounds. After parking his bicycle by the roadside, He Yuzhu walked into the blacksmith shop and said, "Is Master Zheng here?"

He Yuzhu had just walked a few steps into the blacksmith shop when he heard a deep voice coming from inside the shop, "Who is it? What are you doing?" As soon as the words fell, a very strong old man with white hair came out.

He Yuzhu quickly said, "Hello, are you Master Zheng? I was introduced by blacksmith Sun from Nanluoguxiang. I designed something and after looking at it, blacksmith Sun said that only you can make it." After He Yuzhu explained his purpose, he quickly took out the blueprint he had drawn from his pocket and handed it to Zheng Laoguai.

Old Monster Zheng first looked at He Yuzhu, then took the drawing handed over by He Yuzhu and started to look at it. After looking at it for a while, Old Monster Zheng said, "Your thing doesn't look complicated, but ordinary blacksmith shops really can't make it. I can make your thing, but the price is a bit expensive, young man."

When He Yuzhu heard that it could be done, he immediately said happily: "Master Zheng, as long as you can make it, the price is not a problem. But there is one thing I want to tell you first. The drawing I drew is just the most primitive idea. I will know whether it can be used after the product is made. So I may have to trouble you a few more times in the future. I hope you don't mind when the time comes."

After hearing this, Old Monster Zheng laughed and said, "Young man, as long as you pay, you can do whatever you want. Why should I mind?"

He Yuzhu chuckled and said, "As long as you don't mind, I'm sure you won't lose a penny."

Zheng Laoguai looked at the blueprint for a few more times and asked, "Young man, what is this blueprint about? Can you tell me about it?"

When He Yuzhu heard Zheng Laoguai's question, he hurriedly walked to Zheng Laoguai, pointed at the thing on the drawing and began to explain to Zheng Laoguai: "Master Zheng, this thing I drew is used to make artificial meat. When the time comes, grind the soybeans into powder, and then add the soybean powder from this hole, and then let the screw rotate quickly. After the screw rotates, it will move forward with the added soybean powder. Leave a very small outlet in front of the screw, and the soybean powder will be squeezed out little by little by pressure. The squeezed soybean powder becomes what I call artificial meat."

After listening to He Yuzhu's description, Zheng Laoguai immediately said, "I understand what you said. The screw you drew is equivalent to a drill bit. This screw drills into the soybean powder you mentioned, but because the opening in the front is small, the soybean powder cannot be fully discharged in time. This will generate a very high temperature at the exit, and when the soybean powder comes out of the exit, it becomes the artificial meat you mentioned."

After listening to Zheng Laoguai's explanation, He Yuzhu couldn't help but say admiringly: "Master Zheng, you are really amazing. What you said is similar to the principle of what I draw. So how long will it take for me to finish this thing I draw?"

After hearing this, Old Monster Zheng thought about it in his mind and said, "I have never made this thing, but judging from the drawing, it can probably be made in one day. I just don't know how it will turn out."

After listening to this, He Yuzhu asked, "How much does it cost to make this thing?"

Zheng Laoguai looked at the size drawn on He Yuzhu's drawing, estimated the amount of iron needed to make it, and said, "It will cost about 10 yuan to make this thing, including labor and materials."

After hearing the price Zheng Laoguai said, He Yuzhu readily took out ten yuan from his pocket and handed it to Zheng Laoguai, saying, "Then I'll trouble you, Master Zheng. Can I come and get it after get off work tomorrow night?"

Zheng Laoguai took the money handed over by He Yuzhu and said readily: "No problem, come and get it after get off work tomorrow."

After He Yuzhu had a brief chat with Zheng Laoguai for a few more words, he left Zheng Laoguai's blacksmith shop and walked towards his home in Nanluoguxiang.
